FEMA Mobile App
In addition to getting local alerts, FEMA has introduced their own app that allows you to receive alerts to your mobile devices for a variety of events and general life safety reminders.
This app will notify you of severe weather events, give you safety tips, help you locate a shelter and even allows you to upload event photos to assist first responders and emergency planners. In addition to these great resources, this app is capable of alerting about your at home life safety considerations like changing smoke alarm batteries.
